Cold Start Issue

Post by JOH »

Hi all,

My injected Scala is taking two or three turns of the ignition to get it started from cold. Seems like fuel is not getting through on first / second turn then fires up fine.
I've heard talk of 5th injector being the culprit although are replacements available? Any suggestions?
Thanks!

no need to post the same thing 3 times

I'd recommend you to get a fuel pressure tester. you should check the operation of the cold start injector and thermo time switch. lots online about this stuff

this might be useful too:

Might be a good idea to test the 5th injector before buying a new one as could be various things.

Remove the 5th injector and place it in a jar, start up the engine and see if any fuel comes out.

The 5th injector is controlled by a thermo switch on the main coolant outlet on the the front of the head, there is a guide to testing the thermo time switch in the Haynes manual.

It was my daily driver, not a toy.

I needed a practical solution and it worked, I'm not a purist!

Was fine for 12 years and I'd tried all the rest? 🤔👍
